Review of Exact Linearization Method Applied to Power Electronics System

Abstract

Power electronic switching converter is a typical nonlinear systems, it is difficult to solve the problem for power electronics system modeling and control by traditional linear control theory. With the development of power electronics and control theory, exact linearization method has been applied to power electronic systems. First, the basic mathematics of differential geometry is introduced. The basic knowledge and implementation conditions for single-input single-output(SISO) system's input- output linearization, single-input single-output system's state feedback linearization, multi-input multi-output (MIMO) system's state feedback linearization is also introduced. Second, the applications of the exact linearization method which is applied in the field for power electronic switching converters, three-phase PWM rectifier, inverter, active power filters(APF), motor control, is introduced. Finally, the exact linearization method in power electronics systems research trends is proposed.
